At the very heart of Lübeck’s historical centre a new commercial building was constructed. The building had to be inserted very carefully into the UNESCO-listed Old Town. For this reason the roof played a major role in the design concept. The roof consists of 16 shells in reinforced concrete that have a thickness of 14 cm each. In plan view the shells are trapezoids that are arranged in alternating alignments. The shells span 8.75 m in cross direction and up to 28 m in machine direction.
